BACKGROUND OF INVENTION

The subject invention relates to a method and apparatus for an insert-receiver system for relocatable buildings. In an embodiment, the subject insert-receiver system can be incorporated with relocatable modular buildings.

Traditionally, relocatable buildings rest upon the ground or upon a foundation layout made up of, for example, concrete blocks and/or wood blocks at a site. In order to lift the relocatable buildings to, for example, relocate them, connectors are often located on the building. These connectors must be strong enough to support the weight of the building and be adequately and properly interconnected with the building to allow the building to be lifted without damaging the building.

With a relocatable building, high wind turn over can be a problem. Furthermore, certain applications necessitate additional performance criteria for the building such as dealing with soil content and resistance to rotation. Accordingly, there is a need to fix the building to the ground securely. Relocatable buildings are typically tied down to the ground.

In addition, traditional methods of lifting and transporting relocatable buildings can be time consuming and require extensive labor to be located at the building site. Accordingly, there is a need for a system that provides for a relocatable building to be lifted, moved, secured, and/or transported efficiently.

In an embodiment, a modular and/or relocatable building with a receiver can be placed directly on to the ground or on a block column support 19. In order to secure the modular and/or relocatable building to the ground, an insert 13 with anchor attachment 14 can be used.

Referring to FIGS. 2-4, a specific embodiment of the subject invention can be used to secure a relocatable modular building to the ground. In one embodiment, a helical earth anchor 18 can be used to secure the relocatable building to the ground. The helical earth anchor 18 can be secured to the relocatable building by the insert-receiver system. In an embodiment, the helical earth anchor 18 can have a tie down strap 17. The strap 17 can be connected to an insert for the insert receiver system. In a specific embodiment, the strap 17 connects to a tube 30. As shown in FIGS. 2-3, the strap 17 can connect to the tube 30 at different orientations. The connection can be flush with the front of the insert as shown in FIG. 3A, or alternatively, the connection can longitudinally intersect with the insert as shown in FIG. 2A. A receiver 20 can be formed by affixing a lift tube onto the frame under the floor system 40 of a relocatable building. The tube 30 can slide into the lift tube receiver 20 to form a tight fit. The tube 30 can be slid to the end 21 of the lift tube receiver 20. Once the earth anchor 18 is secured to the relocatable building through the insert receiver system, the earth anchor 18 can be driven into ground. The relocatable building can be secured to the ground through the tightening mechanism of the strap 17 of the earth anchor 18.

The placement of the receivers can help distribute the load of the relocatable building when being lifted. In one embodiment, a relocatable building can be constructed with only one receiver on each end of the building frame. In another embodiment, two complementary insert-receiver systems can be connected to each end of the frame of a relocatable building or building section. Referring to FIG. 4, four receivers can be positioned at one end of a relocatable building and four receivers can be positioned at the other end of the relocatable building. FIG. 4 shows a floor plan and chassis 4 of a relocatable modular building where two building sections are married. In an embodiment, a securing insert 30 can be inserted into each of the receivers 20 to prevent the relocatable building from moving.

During fabrication of a relocatable building, one or more receivers 2 can be affixed to the frame or walls of the modular and/or relocatable building. In order to transport a modular and/or relocatable building to a site, an insert with a lifting attachment can be slid into one or more of the one or more receivers affixed to the frame or walls. In an embodiment, the lifting attachment can be a bracket attachment 23. A crane or lift can be connected to the bracket attachment 23 of the inserts that are in the receivers 2 and move the relocatable building onto a truck or trailer. Once the modular and/or relocatable building is placed on the truck or trailer, the lifting inserts that are in the receivers 2 can be removed and replaced with inserts for truck or trailer transportation. In one embodiment, inserts with a tie down attachment 14 as shown in FIG. 1D can be inserted into the receivers 2 and secured to a trailer or bed of a truck with a chain (not shown).

In a further embodiment, inserts with a hitch attachment can be inserted into receivers 2 on one end of the modular and/or relocatable building such that the modular and/or relocatable building can be hitched to a vehicle or trailer. In an embodiment, a single insert can be used for both lifting the modular and/or relocatable building and securing the modular and/or relocatable building to a truck or trailer for transportation. In one embodiment, at a building site, the transportation inserts can be removed and replaced with dolly inserts, for example as shown in FIG. 1G, to roll the modular and/or relocatable building into place at the building site. FIG. 6 shows an embodiment of a dolly insert in use. The height of the modular and/or relocatable building on the dolly inserts can be adjusted by, for example, a crank 6 on the dolly 16. Once the modular and/or relocatable building is in place on a foundation layout, the dolly inserts can be removed and replaced with securing inserts. For example, the securing insert can be a have a tiedown attachment 14 to be secured to a helical earth anchor 18. A helical earth anchor 18 can be set into the ground and a tiedown strap 17 engaged with the tiedown attachment 14 of an insert can be tightened to secure the modular and/or relocatable building in place.

Referring to FIGS. 5A and 5B, an embodiment having an attachment 14 and a swivel attachment 15 is shown. The swivel attachment rotates around pin 16. The swivel attachment can allow the chain, strap, or other means for attaching to the swivel attachment to be oriented at a variety of angles with respect to the attachment 14 and, therefore, with respect to the receiver into which the insert is inserted.

In an embodiment, the insertion of an insert into a receiver can be performed by sliding the insert into the receiver until the tip of the insert reaches the back end of the receiver, and the removal of an insert from a receiver can be performed by sliding the insert completely out of the receiver.
